OIL-CUP.

Application filed October 8, 1920.

To all whom it may concern Be it known that I, ALBERT C. GRUnwALn, acitizen of the United States, residlng at Chicago, in the county of Cookand State of Illinois, have invented a new and useful Improvement inOil-Cups, of which the following is a specification.

This invention relates partlcularly to 011 cups adapted to be applied tobearings where it is not convenient to employ forced feed.

The primary objectis to provide an improved oil cup which may be readilyrefilled, and which is adapted to effectively exclude dust and grit.

The invention is illustrated in its preferred embodiment in theaccompanying drawing, in which Figure 1 represents an elevational v ewof the improved oil cup; Fig. 2, a plan yiew of the same, in a closedcondition; Fig g3, a plan view of the same in open condition; Fig. 4: aninner view of the cap employed; and Fig. 5 is a detail section of thecover and upper part of the oil cup.

In the construction illustrated A represents a cup or elongated tubularmember, which is provided at one end with a threaded nipple A and whichis equlpped at the opposite end with a cap A The tubular body A andnipple A} are preferably formed integrally by drawing a steel disk intocup form, the bottom port on of the cup being contacted to form thenipple and perforated to provide a passage through which oil may pass tothe bearing. In the illustration given, the cup is equipped at thislower portion with a wick B, which extends through the tubular nipple AThe cap A is preferably stamped from a disk of sheet metal. It has theupwardly dished or semispherical top portion 1 and the depending flange1 The cap is provided at its apex with a central perforation 2, and atsome distance therefrom with an elongated perforation or slot 3. Themetal of the cap is struck outwardly at points 4;, thus providing stops.Mounted on the cap is a segmental closure 5, which is curved tocorrespond with the curvature of the cap. The member 5 is preferablyformed from sheet metal. It is provided at its apex with a perforatedpivotal portion 5*, and is provided at its periphery with a down-turnedflange 5", which embraces the flange 1 the Specification of LettersPatent.

lower edge portion of the flange 5 being spun inwardly beneath the edgeof the flange i as indicated at 5. The segmental closure 5 is connectedwith the cap at its apex by a rivet 6, which serves as a pivot the rivetder flexure, thus holding the closure tight against the top surface ofthe cap. At the extremities of the flange 5 the metal is extended andcurved into cylindrical form, to provide finger pieces 8, by means ofwhich the closure may be swung about the vertical pivot 6. The segmentalclosure 5 presents sharp radial edges 9, adapted to scrape the outersurface of the cap A clean throughout the arc of movement. Such a closefit is secured by the construction employed as to effectively excludeall dust and grit from the oil cup.

The improved oil cup is adapted for use in connectionwith the bearingsof stationary engines, in connection with the bearings for springs ofautomobiles, and in various other situations. The improved device isexceedingly simple in construction, capable of being manufactured atsmall cost and thoroughly effective for its purpose. The cup may be ofconvenient size to properly lubricate an ordinary bearing for a periodof several weeks, without the necessity of refilling the cup in themeantime.

In the manufacture of the device, the cap and the closure appliedthereto, may be assembled before applying the cap to cup A. The cap maythen be forced onto the cup with a close fit, which will effectivelysecure it in position.

What I regard as new and cure by Letters Patent, is:

1. A device of the character set forth, comprising an oil cup equippedat one end with a cap having a bowed top wall and a depending flangeembracing the cup, said top wall being provided at some distance fromthe center with a perforation through which oil may be introduced, and asegmental closure surmounting said cap and swivelly connected therewithby a central vertical pivot, and a leaf spring engaging the innersurface of the top wall of the cap, said spring being engaged by theinner end of said pivot and held under flexure thereby.

2. A device of the character set forth; comprising an oil cup equippedat one end 7 with a cap comprising a bowed top wall and. a dependingflange which embraces the up-' per portion of said cup, said top wallbeing provided with a perforation through which oil may be introducedand having a depend ing flange with an inturned lower edge engagingthelower edge of the flange of said cap, theflange of said closure beingpro- 10 vided with a finger piece, ,a leaf spring bearing against theinner surface of said cap, and an axial pivot connecting said closure tothe central portion of saidcap and to said sprin for the purposesetforth. 15
